Custom django management command with appended parameters

My team runs a custom test suite pretty regularly. When we want to run the whole thing, we do

./manage.py test --keepdb --failfast --settings=AE.test_settings

When we want to run tests on a specific app, we do the same, but with the app name include.

I'd like to make a custom management command that, when called, will run the default test suite, but append the --keepdb, --failfast, and --settings=AE.test_settings params. Ideally something like

./manage.py aetest

That can also be run with app names, such that

./manage.py aetest registration

Would be the same as running

./manage.py test registration --keepdb --failfast --settings=AE.test_settings

My attempt so far is

from django.core.management.base import BaseCommand, CommandError
from django.core import management

class Command(BaseCommand):

    def handle(self, *args, **kwargs):
        positional_arguments = [
            '--keepdb',
            '--failfast',
            '--settings=NJ.test_settings',
        ]
        for item in args:
            positional_arguments.append(item)
        keyword_arguments = {
            'settings': "AE.test_setings",  
        }
        keyword_arguments.update(kwargs)
        management.call_command("test", *positional_arguments, **keyword_arguments)

If I try to pass further positional arguments, my command errors out in such a way as to imply they were never passed. And the keyword argument never makes it to the call_command (the command runs with my default settings.py file)

Any idea how I can have this management command accept additional positional and keyword parameters, but append the desired ones automatically?

Thanks!
